How do we define trafficking?

Here are the UN and US definitions of trafficking:

United Nations Convention Against Transnational Organized Crime, Supplemental Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children

'“Trafficking in persons” shall mean the recruitment, transportation, transfer, harbouring or receipt of persons, by means of the threat or use of force or other forms of coercion, of abduction, of fraud, of deception, of the abuse of power or of a position of vulnerability or of the giving or receiving of payments or benefits to achieve the consent of a person having control over another person, for the purpose of exploitation. Exploitation shall include, at a minimum, the exploitation of the prostitution of others or other forms of sexual exploitation, forced labour or services, slavery or practices similar to slavery, servitude or the removal of organs;

The recruitment, transportation, transfer, harbouring or receipt of a child for the purpose
of exploitation shall be considered “trafficking in persons” even if this does not involve any of the means set forth in subparagraph (a) [see above] of this article;'
